"OTTAWA -- Canada plans to expand one of its most prized parks to more than six times its current size in a move to help protect the habitats of grizzly bears, caribou and other species, the government said on Tuesday.

Ottawa unveiled legislation to increase the size of the Nahanni National Park in the Northwest Territories to more than 30,000 square km (11,600 square miles) -- an area two-thirds the size of Switzerland -- from the current 4,800 square km."
